题目内容

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Luckily, you’ve got a thing that sends out energy at small chips（芯片） in everyone’s name tag（标签）.The chips send back name, job, hobbies－whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a new age of using RFID technology.

An RFID tag with a small chip can be fixed in a product, under your pet’s skin（皮肤）, even under your own skin. Some RFID tags have no energy source because they do not need it. The energy comes from a scanning device（扫描装置）, which sends out energy and starts up the tag immediately.

Such a tag carries information to that object, and the information can be renewed. Already, RFID technology is used for recognizing（识别） each car or truck on the road and it might appear in your passport. Doctors may put a small chip under the skin to get a patient’s medical records. At a nightclub in Paris or in New York the same chip might get you to pay for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The idea was that computer chips could be put everywhere and send information in a smart network that would make life simpler.

RFID tags are a small part of this situation. “The world is going to be a connected set of personal small devices.” predicts Dr. J. Reich. But some people are nervous about the possibilities of such technology. It goes too far tracking（跟踪）school kids through RFID tags, they say.

When Marconi invented radio, he thought it would be used for ship-to-shore communication, not for pop music. Who knows how RFID and other technologies will be used in the future. Here’s a wild guess: Not for buying milk.

1.The article is intended to______.

A. warn people of the possible risks in adopting RFID technology

B. explain the benefits brought about by RFID technology

C. convince people of the uses of RFID technology

D. predict the applications of RFID technology

2.We know from the passage that with the help of RFID tags, people_____.

A. will have no trouble getting data about others

B. will have more energy for conversation

C. will have more time to make friends

D. won’t feel shy at parties any longer

3.Passive RFID tags chiefly consist of____.

A. scanning devices B. radio waves

C. batteries D. chips

4.Why are some people worried about RFID technology?

A. Because children will be tracked by strangers.

B. Because market competition will become fiercer.

C. Because their private lives will be greatly affected.

D. Because customers will be forced to buy more products.

Imagine that you are the first person ever to see Hawaii. What would be the first thing you would set foot on?

The beach, naturally. There are hundreds of miles of beaches on the twenty islands of Hawaii. These islands cover 1,600 miles and are about 2,300 miles west of California. Most of them are covered with fine white sand. They are thought to be among the finest beaches in the world.

Another wonderful thing about the beaches of Hawaii is the water temperature. The year-round average（平均） temperature of the water at the famous Waikiki Beach is 23℃!

The same is true of air temperature. In fact, there are no real seasons in Hawaii. There is a difference of only two or three degrees between the hottest day of summer and the coldest day of winter. That's why the Hawaiians don't have a word for weather in their language.

Perhaps the nicest thing about Hawaiian beaches are the waves. The earliest settlers（定居者） in Hawaii, the Polynesians, quickly learned how much fun it was to ride the waves. They developed a sport which is now very popular on the islands called body surfing. You go out into the ocean, wait for a big wave to come towards you, jump on it, and ride it all the way to the beach.

Now imagine once again that you are the first person ever to set foot in Hawaii. What do you think would be the second beautiful thing you would notice?

Would it be those strange triangles（三角形状物） rising out of the water hundreds and hundreds of meters high? What are those beautiful things? They are volcanoes（火山）, of course. These volcanoes are not just a part of the islands. They made the islands at first. Because of them the islands are still growing.

The most famous volcano on Hawaii is Mauna Loa. It is the world's most active volcano. It has been erupting（喷发） for thousands of years. Even when it isn't erupting, smoke comes out of the earth from a thousand little holes.

In 1950 Mauna Loa erupted for twenty-three days. That erupting produced the greatest amount of lava（熔岩） in modern history. In 1960 it erupted again. That time it added a kilometer of beach to the island. Because Mauna Loa has erupted so often, it has become the biggest（but not the tallest） mountain in the world.

These volcanoes could be dangerous to the population of Hawaii. In fact, Hilo, the second largest city in Hawaii, is built just under Manna Loa. The volcano could erupt at any time. Most people believe that it will erupt sometime in the next twenty-five years. But the people of Hilo do not seem worried. They live with the danger as part of their lives.

1.According to the passage, what are the two most beautiful things in Hawaii?

A．Waves and cities. B．Beaches and language.

C．Volcanoes and beaches. D．Volcanoes and people.

2.Which is NOT the reason why the Hawaiians don't have a word for weather in their language?

A．There are no real seasons in Hawaii.

B．The temperature of the water at one of the beaches is always 23℃.

C．The Hawaiians feel almost the same in the hottest day and coldest day.

D．There is not much difference in air temperature all the year round in Hawaii.

3.What should be the meaning of “body surfing”?

A．Riding waves. B．Body-building.

C．Sea bathing. D．Jumping into the sea.

4.It can be inferred that ________ according to the passage.

A．volcanoes are more active because the area of the island is enlarging

B．the visitors to Hawaii can probably see more than one active volcano

C．Mauna Loa is the tallest mountain in the world because it has erupted so often

D．people in Hilo are sure that more visitors will come because of volcanoes

It’s hard to believe how times have changed since the first modern Olympics were held in Athens, Greece, on 6th April 1896. Over one hundred years ago, there was very little reliance（dependence）on modern technology. There were no landing mats（海绵垫）, no stopwatches and no photo finishes. In fact, cameras and stopwatches were not used until the 1932 Olympic Games in Los Angeles, the USA.

Today technology has completely revolutionized（changed） sports. Take sports equipment（装备）for example. Starting blocks are now equipped with electronic pressure sensors（传感器）, which provide exactly correct race time and also help to catch runners who “jump the gun”. As athletes cross the finishing line, special digital cameras can also easily decide the winner. The clays of “dead heats” are gone.

Athletes have also benefited（受益） from technological developments. Body-hug-ging suits, which reduce（减少） wind drag, can help cut up to one-tenth of a second from runners’ race times. Top athletes are even provided with tailor-made sports shoes. These shoes are made to fit the athlete exactly—and there are even air compartments in the shoes that can be filled to meet each runner’s individual needs.

Technology has also changed the way that many sports are performed. Take one example—the pole vault（撑杆跳）. The inclusion of a landing mat obviously made a big difference to the vaulting style（方式）as athletes no longer needed to worry about hurting themselves as they fell. Without these worries, athletes could obviously jump higher. These days, polevaulters do not even need to worry about the crossbar as the uprights are now fitted with light-emitting diodes（LEDs） that measure（测量） how high the athlete vaulted. Technology has even been to the advantage of swimmers. New pools have been designed to reduce wave interference and sports scientists have even developed a new style of swimming that increases buoyancy and reduces drag in the water.

The increasing importance of these technological developments has led many sportsmen to suggest that the “Olympic spirit” is being lost in a rush to break records and win medals. Many developing countries say that technology has become too important in sport and that athletes from developing countries that cannot afford such technology are disadvantaged. There are no easy answers but one thing is sure—we cannot turn back time. Technology cannot go backwards.

1.How many pieces of high-tech sports equipment are mentioned in paragraph 2 and 3？

A．One. B．Two.

C．Three. D．Four.

2.The underlined phrase “dead heats” means “________”.

A．sports equipment which was out of date

Everyone needs friends. There is an old saying, “Friends are God’s way of taking care of us.” But how do you find real friendship and keep it?

The American writer Sally Seamans tells young students some smart ways to find friends. Sally says finding friendship is just like planting a tree. You plant the seed(种子) and take care of it to make it grow.

First, you should choose a friend. What makes a good friend? It is not because a person has money or good looks. A good friend should be kind and patient(耐心). For example, if you have a bad day, a good friend should listen to your complaints and do his best to help. To make a good friend, you cannot be too shy. You should make each other happy and share your lives.

But things cannot always be happy. Even the best friends have fights. What should you do when you have a fight with your friend? You have to talk to him or her. When there is no one around, have an honest talk. If he or she doesn’t want to talk, you could write a letter.

There are three steps to being friends again:

Tell him or her how you are feeling; say what your friend has done wrong, and explain why you did this or that. Remember that friendship is the most important thing in your life.

1.Sally wants to tell students the ways to .

A. find friends B. plant trees

C. get happy D. keep fit

2.What makes good friends? A good friend should .

A. be lovely and cool B. be kind and patient

C. have lots of money D. have good looks

3.According to the text, you can ___________ your friend after a fight.

A. buy a present for B. never say a word to

C. have dinner with D. write a letter to

4.What is the best title of the text?

A. Teenagers and friendship. B. The good friends around you.

C. The trouble of growing up. D. The care and keeping of friends.

A group of frogs were traveling through the woods, and two of them fell into a deep hole. When the other frogs saw how deep the hole was, they told the two frogs that they were hopeless to be alive. But the two frogs didn’t believe it. 1. . The other frogs kept telling them to stop and wait for their death. Finally, one of the two frogs gave up and fell down. Soon he died.

The other frog continued to jump as hard as he could. Once again, the crowd of frogs shouted at him and told him to stop and just wait to die. 2. .

When he got out, the other frogs said: “Didn’t you hear us?” The frog explained to them that he was deaf. 3. .

The story teaches us two lessons. 4. . An encouraging word to someone who is down can cheer him up and help him make it through difficulties. Secondly, a destructive (消极的) word to someone who is down can make him give up and die. So be careful of what you say.

Speak life to those who cross your path. It is sometimes hard to understand that an encouraging word can go such a long way. It is great for a person to take the time to encourage another.

A. Then the two frogs began to stop jumping

B. But he jumped even harder and finally he made it

C. Firstly, there is power of life and death in the tongue

D. So he thought they were encouraging him at that time

E. They tried to jump up out of the hole with their efforts
